In this article, we'll uncover five surprising facts about the MGB that you may not know, shedding light on the hidden aspects of this beloved sports car.

The origins of the MGB's engine

The BMC B-Series engine, which powered the original MGB, has a fascinating backstory that many enthusiasts may not know. Initially developed in the late 1940s for practical, everyday vehicles like sedans and commercial vans, this engine was never intended for a sports car. However, MG engineers saw potential in its robust design and decided to adapt it for the MGB, introduced in 1962.

To make the B-Series engine suitable for the MGB, significant modifications were made. The 1.8-litre version was chosen, and it was enhanced with a reworked cylinder head, a higher compression ratio, and twin SU carburettors. These changes transformed the engine from a workhorse into a capable powerplant for a sports car, delivering around 95 horsepower. While this might seem modest, it provided the MGB with a solid balance of performance and reliability.
